Custom function tool in the Responses API flat format.

The Responses API uses a flat structure (name/description/parameters at top level) unlike Chat Completions which nests them under a "function" key:

Responses API: {"type": "function", "name": "add", "parameters": {...}} Chat Completions: {"type": "function", "function": {"name": "add", ...}}
